remuxing h.264 with other fps in .mkv

[Thunderbolt8]

I want to demux the h.264 videostream of a .ts file, running with 25 fps, and then muxing it together with a 23,976 fps audio file as .mkv, using mkvmerge. I will create a .txt file stating

# timecode format v1
Assume 23.9760

and then use it with the video stream's timecodes @general track options in mkvmerge.
so,

1. will it work properly this way and
2. will there be any loss of (video) quality when doing so ?

Thanks!

Under format specific options there is a setting called "FPS". I have been able to use it for some H264 videos instead of a timecode file. But a timecode file should probablu work as well.

I use the Timecode Option very often in mkvmerge for my HDDVD encodes.
I encode to original 23.976fps and mux it to 25fps to match German PAL Audio (when i have no DD+ in German)

There no loss of Quality and on clean Sources it should work perfect
